> It should be configurable if data stored by NIO buffer or not.
> It means data stored outside of java heap. Create, destroy in the external memory should be managed by infinispan. 
> With this solution gc can run fast however infinispan node can handle huge amount of memory. 
> In the current case the optional size of the java memory of a node is smaller or equals than 4GB because of garbage collection issues above 4GB.
> See a similar thing in EHCache BigMemory.
